The quasi-score function, as defined by Wedderburn (1974) and McCullagh (1983) and so on, is a linear function of observations.
The generalized quasi-score function introduced in this paper is a linear function of some unbiased basis functions, where
the unbiased basis functions may be some linear functions of the observations or not, and can be easily constructed by the
meaning of the parameters such as mean and median and so on. The generalized quasi-likelihood estimate obtained by such a
generalized quasi-score function is consistent and has an asymptotically normal distribution. As a result, the optimum generalized
quasi-score is obtained and a method to construct the optimum unbiased basis function is introduced. In order to construct
the potential function, a conservative generalized estimating function is defined. By conservative, a potential function for
the projected score has many properties of a log-likelihood function. Finally, some examples are given to illustrate the theoretical
results.

Starting with its early twentieth century origins, the development of Labor Economics is traced to the present. We describe
an intellectual revolution in which an earlier tra-dition that focused primarily on the institution of the labor union has
been replaced by a perspective that emphasizes the various roles played by labor markets in an eco-nomic system. That earlier
tradition contained very significant ideological elements, whereas its successor deals much more with the world of ideas.
In the course of the debate, which still continues, ideas triumphed over ideology and created modern Labor Economics. 相似文献

The Exclusion of Disabled People from Positions of Power in British Voluntary Organisations 总被引:1,自引:1,他引:0
Robert F. Drake 《Disability & Society》1994,9(4):461-480
Disabled people are excluded in various ways from a wide range of social privileges, activities and institutions. Voluntary and charitable organisations promote themselves as champions of disabled people in their struggle for access to the ordinary choices and opportunities of everyday life. This paper reports the findings of an empirical study which demonstrate that in voluntary agencies governed by able-bodied people, disabled people are excluded from positions of power and influence, and they experience the same sorts of barriers and constraints as those with which they are confronted in the wider world. Furthermore, the development of agencies governed by disabled people themselves is constrained by their lack of access to money, staff and other resources. 相似文献

We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post
aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities
may vary. If they analyze the same situation in more detail, their refined analysis should preserve their preferences among
acts. However, ex post aggregation could bring about a preference reversal on the group level. Ex post aggregation thus depends
on how much information is used and may keep oscillating (“flipping”) as one keeps adding more information.

In a general model of indivisible good allocation, S?nmez (1999) established that, whenever the core is nonempty for each
preference profile, if an allocation rule is strategy-proof, individually rational and Pareto optimal, then the rule is a
selection from the core correspondence, and the core correspondence must be essentially single-valued. This paper studies
the converse claim of this result. I demonstrate that whenever the preference domain satisfies a certain condition of `richness',
if the core correspondence is essentially single-valued, then any selection from the core correspondence is strategy-proof
(even weakly coalition strategy-proof, in fact). In particular, on the domain of preferences in which each individual has
strict preferences over his own assignments and there is no consumption externality, such an allocation rule is coalition
strategy-proof. And on this domain, coalition strategy-proofness is equivalent to Maskin monotonicity, an important property
in implementation theory.

A comprehensive set of variables that have been supported as contributing to overall health and general well-being were analyzed to determine their simple structure using factor analysis and their relative contribution using Pearson correlation. The contributors to general well-being had been theoretically grouped into: emotions, beliefs, temperaments, behaviors, sittuations, experiences and health. The empirical factor structure was compared with the theoretical structure used to develop the variables. Stability was investigated by comparing results with those of another geographically separated group. All subjects were normally functioning working adults. The results demonstrated the feasibility and potential usefulness of using self-report questionnaires with multivariate procedures to measure components of the global general well-being concept. 相似文献

Abstract This study examines the contentions of two recent perspectives on rural economic organization and their implications for poverty. Building from (1) agrarian political economy and (2) the rural restructuring literatures, we present a comparative regional analysis of how farming patterns and other aspects of economic organization differentially affect poverty in rural areas. Data are based on 2,349 nonmetropolitan U.S. counties for the 1970–1980 period. Nonhired labor-dependent, family-operated farming (smaller and larger family farming) has relatively similar cross-regional effects on rural poverty. The effects of industrialized farming are more spatially variant, suggesting that this type of farming is integrated into regional political economies in different ways than are simple commodity units. However, farming patterns have only a small effect on rural poverty relative to other factors, such as the local employment structure, characteristics of the population, and geographic location. The results of this study highlight the need to move beyond the farm sector to understand both the dynamics of this sector and the socioeconomic consequences of rural restructuring. More broadly, the study underscores the importance of testing general sociological relationships under different spatial (e.g., regional) contexts. 相似文献

Gerhard Meyer Ph.D. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1992,8(1):11-20
The development of the gambling market in the Federal Republic of Germany since the middle of the seventies and data on pathological gamblers seeking help are described. The continuously increasing supply, together with increases in turnover, was followed-with some temporal delay-by an increase in the number of gamblers who sought advice and treatment. Preliminary measures taken by the health authorities as well as some consequences of pathological gambling are discussed.This article is a translation of a German article published in: Deutsche Hauptstelle gegen die Suchtgefahren (1990): Jahrbuch '91 zur Frage der Suchtgefahren.
